Story highlights

Alex Thomson renowned for his daredevil yachting stunts

Thomson's mast and keel walks were big hits on YouTube

The 40-year-old Briton targets victory in 2016 Vendee Globe

He does not rule out doing another stunt in the future

His daredevil stunts have attracted over 3.5 million hits on YouTube and reached uncharted waters for sailing, but for his next trick Alex Thomson just wants to get back to doing what he does best -- circumnavigating the globe faster than anyone else.

His "crazy ideas" have ended up with the 40-year-old walking along the keel of his Hugo Boss yacht and then -- even more daringly -- scaling the height of its huge sail before diving into the water.

Thomson was dressed for both stunts in the stylish menswear associated with his sponsor. Their longstanding relationship dates back to 2003, with Thomson having made headlines in a more conventional sporting manner through his exploits in long-distance ocean racing.

As far back as 1999 he became the youngest skipper to win a round the world race, and he's a multiple record-holder for distance covered in 24 hours at sea.

The planning required for the America's Cup is on a similar scale to the Vendee -- but instead of being part of a big crew, Thompson will be on his own as he negotiates his way around dangerous oceans at the helm of a 10-ton, 60-foot yacht.

"The boats are absolute beasts with a sail area of three tennis courts alone," said the Welshman, who was born in the coastal town of Bangor.

"It very much depends whether you are physically fit enough to do this kind of thing."
